GM does not allow to accumulate a single satosh.
How will GM issue a withdrawal if it spams 800 satoshi daily?
I don't have credits at all in my account.
Amount to be paid is to small. 0.002btc is the minimum amount.
Remember this is for each single contract. If you have 10 contracts of 1TH, 10 contracts will be pending some time until the threshold of each contract is above 0.002btc
